5o ing a recess t' in the bolt B, and passing The manner of applicationof this lock to through the slot e of the barrel or bearing b, one formof door to which it may be applied is shown in Fig. 3, the stiles XiandY of the overlapping doors being` shown in dotted lines. The stile ordoorYis shown as carrying the lock, while the stile or door X receivesthe bolt. It is evident that this lock is adapted to all forms ofsliding overlapping doors or to doors which overlap a jainb.

In the modification as disclosed in Fig. 9 the lock is shown as adaptedfor use in connection with warehouse, barn, and stable doors. In thismodification the face-plate is shown as having a shoulder G to receivethe abutting edge of the opposite or other door. In this modificationthe rock-shaft is also shown as located between the tumblers` and thebolt, instead of as shown in the other iigures and as heretoforedescribed. The operation, however, is substantially the same.

Having described this invention, what. I claim as new, and desire tosecure by Letters Patent, is-

l. The lock having the laterally-movable bolt, in combination with therock-lever hav-y ing an arm engaging said bolt, and the actuatingmechanism comprising a slide acting z t Nitnessesr upon a second armr ofsaid lever, substantially as set forth. 2. The combination, with thebolt and its inclosing barrel or bearing, of the yrock-lever havinganarm engaging said bolt, the slide engaging a second arm of said leverand having a slot receiving a post or stud of the faceplate of the caseand a second slot, and the tumblers, one having a T-shaped slot and theothers each having two slots connected `by a kcontracted slot, all ofsaid slots being engaged by a lug on said slide, and means for actuatingsaid tumblers and slide, substantially as set forth.

3. In a lock, the combination of the case having its face-plate providedupon the inside with the slotted barrel or bearing, the bolt having atiange at its inner end formed with a guide extension or projectionengaging the slot of said barrel, the spring placed around said bolt andinterposed between said flange and a seat at the outer end of saidbarrel, and means for actuating said bolt, substantially as speciiied.

In testimony whereof I affix my signature in presence of two witnesses.
